Coase Theorem Is Truth or Not？

Coase theorem has the implicit private property right system preference. In the logic sense, if we define “exchange cost”, “exchange right＇s initial allocation” and “final allocation” specially, Coase theorem will be correct in the sense of main - stream western economics logic and methodology, but Coase theorem is equal to perfect competition theory at all at the same time, it has no reality sense. In the empirical sense, Coase theorem is fallacious. A lot of economists including Paul A. Samuelson and Joseph E. Stiglitz have given Coase theorem radically negative comment. Coase theorem＇ s inference must be private property fight firm＇ s efficiency is higher than commonality property right firm＇ s. There are three kinds of evidence in the economic practice, one affirms Coase theorem absolutely, one denies Coase theorem at all, the other contains component denying Coase theorem while it affirms Coase theorem. The post property - right argument is evolution and negation of Coase theorem to a certain extent.     

论科斯定理的真理性

科斯定理具有隐含的私有产权制度偏好。在逻辑意义上,对科斯定理中"交易成本"、"可交易权利的初始配置"、"最终配置"作特定的理解,科斯定理在西方主流经济学逻辑、方法论意义上是正确的,但此时科斯定理完全等价于完全竞争理论,没有任何现实意义。在经验意义上,科斯定理是谬误。科斯定理的逻辑推论必然是私有产权企业比公有产权企业更有效率。在经济实践中,存在着三类证据:完全肯定科斯定理、完全否定科斯定理以及在肯定科斯定理的同时包含着否定科斯定理的成分。"超产权论"是对科斯定理的"革命",是对科斯定理的否定。

西方宏观经济学微观基础研究综述

宏观经济学的微观基础研究,是近30年来西方经济理论界的一个热门研究领域。本文回顾了西方宏观经济学微观基础研究的历史背景,考察了新古典宏观经济学和新凯恩斯主义经济学两大学派围绕微观基础研究而展开的争论,并评述了目前西方宏观经济学超越微观基础研究的最新发展动态。     

Do Investors Overrely on Old Elements of the Earnings Time Series?*

This paper reports an experiment demonstrating that MBA students overrely on old earnings performance when predicting future earnings performance in a laboratory setting. In the experiment, MBA students relied too heavily on old annual ROE information to predict future annual ROE. The experiment shows how a common cognitive error (overreliance on unreliable information) interacts with the structure of the earnings time series to create particular patterns of prediction errors. The results also suggest directions for research on two well‐known anomalies, long‐run overreactions (De Bondt and Thaler 1985, 1987) and post‐earnings‐announcement drift (Bernard and Thomas 1990).     

A Bayesian Model for Estimating Census Undercount,Taking Emigration Data from Foreign Censuses*

The new method of measuring net undercount in a census of population is a variant of demographic analysis and is founded in the belief that the most reliable counts of people are the counts of births and deaths. It has been applied to the 1991 census of England and Wales (E&W). The method has two distinctive features. The first is that it bases its estimates of numbers of emigrants on figures of persons born here and recorded as residents in the 1990–91 censuses of other countries. The corresponding data on immigrants are taken from our own census. The method does not therefore require the data on migratory flows that are an essential component of conventional demographic analysis. The second feature is the Bayesian approach in which (1) each of 30 uncertain elements in the calculations is given an a priori error distribution and (2) three empirical constraints are imposed on the sex-age profile of percentage net undercount. This, in conjunction with a Monte Carlo process, generates an error distribution for net undercount. These merits of the method are offset by the demerit that the calculations must await results from the censuses of the other countries in which substantial numbers of our emigrants reside.     

Do XBRL filings enhance informational efficiency? Early evidence from post-earnings announcement drift

In 2009, the Securities Exchange Commission (SEC) mandated public firms to file their financial statements using eXtensible Business Reporting Language (XBRL). The SEC's main motive behind this mandate is that XBRL filings would enhance the informational efficiency in the stock markets by making financial data easier to use and analyze for a broad range of investors. Using a sample from the first wave of mandated XBRL filers, we find a decline in post earnings announcement drift for the good news portfolio in the post-XBRL adoption period. Instead of a drift associated with underreaction, we find that markets overreact to negative earnings surprises for the bad news portfolio during our observation period, which coincides with the financial crisis. We detect limited evidence that XBRL adoption mitigates overreaction, which is another form of market inefficiency. We also find limited evidence that XBRL particularly benefits small investors.     

Socialism after Hayek: A Post Keynesian Contribution to Burczak's Theory of Social Justice

The paper presents a brief overview of the basic premise of the Burczak's Socialism after Hayek, and shows that Burczak's “applied epistemological postmodernism” presents a unique unifying ground for heterodox economics, breaking down traditional barriers between right and left. This new approach allows us to revisit the Marx-Keynes-Hayek debates in a more constructive way for a unified theory of social justice. However, we argue that Burczak's system does not automatically guarantee full employment, so it cannot be considered an ideal theory of social justice. A Post Keynesian contribution is presented in the form of the Employer of Last Resort (ELR) program which we argue is compatible and complementary to Burczak's theory of social justice. Finally, we argue that an adequate system design of the magnitude proposed here must be infomed by the principles of institutional adjustment as outlined by J. Fagg Foster.     

加入WTO后过渡期我国进口贸易救济体系的完善

2005年开始,主要产业在加入WTO谈判中获得的过渡期大部分结束,进口贸易自由化程度空前提高,进口产品的不公平竞争和进口激增必将对我国产业造成冲击,进口贸易救济工作面临严峻考验。为此要借鉴他国的成功经验,进一步完善我国的贸易救济体系。     

基于“C-2P”模式的薪酬设计研究——以某药业公司销售支持人员的薪酬设计为例

目的:为某药业公司销售支持人员构建薪酬设计方案.方法:分析某药业公司目前薪酬方案存在的问题,构建“C-2P”模式的薪酬设计框架,确定有关参数,并采用层次分析法(AHP)和Delphi法确定相关指标的权重和等级评分.结果:岗位重要性(v)、工作量饱和度(s)和适岗性(m)三个指标加权得到岗位系数(α),综合素质(d)和岗位职责(r)各项指标加权得到绩效系数(β),实际薪酬(W)为工资基数(B)、岗位系数(α)和绩效系数(β)的乘积.结论:此套薪酬设计方案能普遍提高销售支持人员的岗位标准工资,引入绩效考核机制,体现薪酬的公平性和激励性,促进营销团队的稳定与发展,降低企业人才管理成本.
